The DBH 9257 radial shaft seal is a lip seal designed to be mounted on a 24.5 mm shaft and seated in a cavity with a height of 10.50 mm. Its function is to retain the lubricant inside the assembly and prevent the entry of dust, water or contaminating particles. It is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales sells this official brand and advises you so that you choose the right oil seal for your application.

This item is a radial shaft seal from the DBH line, identified with part number 9257. According to the product page data, it corresponds to a shaft of 24.5 mm in diameter and a total height of 10.50 mm. The A 181 design defines the geometry of the lip and the metal body, although the housing diameter is listed as 0 mm in the record, so that data is confirmed against the manufacturer's data sheet before quoting. It is a single-lip seal, with a spring, suitable for rotating shafts.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. In all cases, its function is twofold: to retain the oil or grease and to exclude external contaminants. As it is a wear part, it should be replaced when leaks appear or when the lip shows hardening, cuts or loss of elasticity. It is also used in equipment where axial space is limited and a compact seal is required.

To mount this oil seal, verify that the shaft has the indicated size and that the contact surface is polished and free of burrs. Lubricate the lip with the same grease or oil used in the equipment before inserting it. The 10.50 mm height must match the depth of the housing. If the housing is damaged, consider using an oil seal with a sleeve or an alternative size. Correct alignment between shaft and cavity prevents premature leaks and extends the service life of the seal.
